pls use python do this

Problem 1. Word scores

The first step is to implement some code that allows us to calculate the score for a single word.

The function get_word_score should accept a string of lowercase letters as input (a word) and return the integer score for that word, using the games scoring rules.

Fill in the code for get_word_score in ps3a.py:

def get_word_score(word, n):
"""
Returns the score for a word. Assumes the word is a
valid word.

The score for a word is the sum of the points for letters
in the word multiplied by the length of the word, plus 50
points if all n letters are used on the first go.

Letters are scored as in Scrabble; A is worth 1, B is
worth 3, C is worth 3, D is worth 2, E is worth 1, and so on.

word: string (lowercase letters)
returns: int >= 0
"""
# TO DO...

You may assume that the input word is always either a string of lowercase letters, or the empty string "". You will want to use the SCRABBLE_LETTER_VALUES dictionary defined at the top of ps3a.py. You should not change its value.

Do not assume that there are always 7 letters in a hand! The parameter n is the number of letters required for a bonus score (the maximum number of letters in the hand).

Testing: If this function is implemented properly, and you run test_ps3a.py, you should see that the test_get_word_score()tests pass. Also test your implementation of get_word_score, using some reasonable English words.
